Car amp placement is extremely important. Because the amp puts out so much heat, it needs to have proper cooling and ventilation around it at all times. Improper ventilation can lead to your amp overheating and shutting the sound system down. In extreme cases an amp can cause enough heat to ignite a fire in the location it’s installed, especially if there are other elements to contribute to a fire such as plush carpeting or other materials in the mounting location. There are ways to ensure proper ventilation of your amp. You can use spacers which are placed under the amp to offer air flow around it. You can also use fans which mount on or around the amp to provide proper air flow.
